Thickness of iron distribution box body

The body of an iron distribution box is typically made from cold-rolled steel with a thickness ranging from 0. 8 mm to 1. 5 mm, depending on the model and application.

Material and Construction

Iron distribution boxes are generally constructed from high-quality cold-rolled steel plates (SPCC/DC01 or higher), which are formed through stamping and welding to create a robust and durable enclosure. This material provides high mechanical strength, resistance to deformation, and reliable protection for internal electrical components.

Typical Thickness

Standard indoor boxes: Usually 0. 8 mm to 1. 2 mm, sufficient for supporting internal components and providing basic protection.

Outdoor or heavy-duty boxes: Often 1. 2 mm to 1. 5 mm or more, to enhance impact resistance, corrosion protection, and weatherproofing.

Custom orders: Many manufacturers allow specifying the exact thickness when ordering, for example, a JXF series box can be ordered with 1. 0 mm thickness or other values according to user requirements.

Additional Considerations

Surface treatment: Electrostatic powder coating or anti-corrosion treatments are applied to improve durability and weather resistance. Protection level: Thickness contributes to the overall IP rating and mechanical protection; thicker steel enhances resistance to external impacts and deformation. Compatibility: Standardized thickness ensures compatibility with modular components, DIN rails, and mounting hardware.

In summary, the iron distribution box body thickness is generally between 0. 8 mm and 1. 5 mm, with the exact value chosen based on installation environment, load requirements, and protection needs.

Manufacturers often allow customization to meet specific project requirements.
